Terms & conditions.

The agreement between you and ZaatarLABS when you use our apps or this website.

Effective 25 October 2026

The short version

1. Who you're agreeing with

These Terms & Conditions ("Terms") form a contract between you and ZaatarLABS ("we", "us", "our"), the trading name of Omar Al Homaidi, an independent software developer based in the United Arab Emirates. They apply when you download, install, or use any ZaatarLABS-published app on iPhone, iPad, Mac or Android, when you use The Smart Billing on the web at billing.zaatarlabs.com, and when you use the website at zaatarlabs.com.

The apps currently in scope are: The Smart Dentist, The Smart Billing, The Smart Coach, roCARD, My Pizza Calculator, The Smart Hand Calculator, The Smart Trix Calculator, The Smart Budget, and The Smart Padel. Future ZaatarLABS apps are also covered unless they ship with their own separate terms.

By installing or using any of our apps, you agree to these Terms. If you don't agree, please don't install or use the apps.

2. The stores' terms apply too

Our apps are distributed through the Apple App Store and, for some apps, Google Play. Apple's Licensed Application End User Licence Agreement ("Apple EULA") also applies to your use of the apps. If anything in these Terms conflicts with the Apple EULA, the Apple EULA wins. Apple is not a party to these Terms and is not responsible for the apps or their content — but is a third-party beneficiary of these Terms and may enforce them against you.

If you get an app from Google Play, the Google Play Terms of Service also apply to that download and to purchases made through Google Play.

3. Your licence to use the apps

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use each app on devices that you own or control, as permitted by the store you got it from, and to use The Smart Billing on the web in your browser.

You must not, and must not let anyone else:

4. What it costs

4.1 Subscription apps

The Smart Dentist, The Smart Billing, The Smart Coach and The Smart Budget are offered as auto-renewing subscriptions through the Apple App Store. The current pricing and term length are shown on the App Store listing and in-app before you confirm any purchase.

Buying on our websites. Some of our apps can also be bought on a ZaatarLABS website; every such order is processed by Paddle.com, our online reseller and merchant of record, under Paddle's Buyer Terms, and our Refund Policy applies. Today that is The Smart Billing:

The Smart Billing on the web. The Smart Billing's yearly plans (Basic and Pro) and its Lifetime plan can also be bought at billing.zaatarlabs.com; monthly plans are sold only in the App Store and Google Play. Those orders are processed by Paddle.com, our online reseller and merchant of record: Paddle sells you the plan, charges your payment method, collects any sales tax or VAT, and handles billing questions and refunds, under Paddle's Buyer Terms. A web subscription renews automatically for the same term until you cancel it; you can cancel it, resume it, or change it at any time from Settings → Subscription on the web, or with the link in any receipt email from Paddle, and you keep access until the end of the period you've paid for. Whichever way you buy it (App Store, Google Play or the web), one plan unlocks The Smart Billing on your iPhone, iPad, Mac, Android and the web, under your account.

The Smart Budget Pro is sold as monthly or yearly auto-renewing subscriptions, plus a separate one-time Lifetime purchase (see 4.2). All three plans unlock the same Pro features (currently: Smart Insights story cards on the Insights tab, all advanced reports, and household sharing with your family). The free version of the app remains fully functional for capturing transactions, basic budgeting, basic goals, the dashboard, the anomaly Notable card, and the Spending-by-category, Income-vs-spending, All-transactions, and Anomalies reports.

All Smart Budget Pro plans support Family Sharing — one purchase covers up to six family members in the same Apple Family group, at no extra cost.

4.2 One-time purchases

The Smart Hand Calculator and The Smart Trix Calculator are sold as one-time purchases through the App Store. The Smart Budget Pro Lifetime tier is also a one-time purchase that grants permanent access to all Pro features and never renews. Once you've bought any of these, you can re-download them on any Apple device signed in to the Apple ID that made the purchase, in line with Apple's family-sharing and re-download rules.

4.3 Free apps

My Pizza Calculator and roCARD are free to download and use. We may add optional paid features in the future, but the existing features will not retroactively be put behind a paywall.

4.4 Refunds

Refunds follow the place you bought from:

We don't take card payments ourselves. If you have a problem with the app itself, please contact us and we'll do our best to help.

5. The data and content you put in the app

Anything you create or enter inside our apps — patients, clients, invoices, business cards, transactions, calculations, photos you attach — is your content. We don't claim any ownership of it. As described in our Privacy Policy, most of our apps keep it on your devices and in your own iCloud, and we don't receive a copy. The apps that work with an account (The Smart Billing from version 6.0, The Smart Padel, and The Smart Dentist on Android and the web) store it on our servers so it reaches all your devices and your team; it stays yours, we never use it for marketing, and you can export or delete it at any time.

You're responsible for backing up anything important to you. iCloud sync (when you turn it on) is one form of backup; standalone exports (CSV, PDF, share-out) are another. We are not liable for loss of data caused by device failure, deleted apps, iCloud issues, or anything else outside our control.

5.1 When we keep your records for you

The Smart Billing (from version 6.0) and Smart Dentist for Android, with its web app, keep your records on our servers (Smart Dentist on iPhone, iPad and Mac, and its web app for them, keep the clinic in your own iCloud). When those records are about other people, such as your clients, patients or customers, you (or your business) are the controller and ZaatarLABS processes them for you, as your processor. These terms are our agreement for that, including under the EU and UK GDPR (Article 28), and you accept them by using these apps with an account:

6. Acceptable use

You agree not to use any ZaatarLABS app or this website to:

If you use The Smart Dentist, The Smart Billing, or The Smart Coach to manage records of your patients, clients, or customers, you are the data controller for those records. You're responsible for collecting any consents you need from those individuals, for following the rules of your profession or jurisdiction (record-keeping, confidentiality, data-protection law, including any rule on where your records must be stored), and for keeping your device secure. For the apps that keep your records on our servers, section 5.1 sets out how we process them for you.

7. The apps are tools, not professional advice

Our apps are productivity, CRM, finance, and calculation tools. They are not medical devices, accounting platforms, legal advice, or financial advice. Outputs the apps generate — including dental charts, treatment-plan summaries, invoices, reports, profit calculations, and budgets — are working aids based on the information you enter. You remain solely responsible for the professional, clinical, financial, or business decisions you make using them. Always cross-check important figures before you act on them, and consult an appropriately qualified professional when you need professional advice.

8. Updates and changes to the apps

We may update the apps from time to time to add features, fix bugs, improve performance, or stay compatible with new versions of iOS. The minimum supported iOS version may change in future updates. We don't promise to keep updating any specific app forever. If we ever decide to retire an app, we'll do our best to give reasonable notice on this site or in-app, and the App Store re-download rules and your iCloud copy of the underlying data are unaffected.

9. Termination

You can stop using any app at any time by deleting it from your device. Your subscription, if any, runs until the end of the current period (manage cancellation in the App Store).

We may suspend or end your licence immediately if you materially breach these Terms or use the app in a way that creates legal or security risk for us, for Apple, or for other users. If your licence ends, you must stop using the app and (if relevant) delete it.

10. Disclaimer of warranties

To the maximum extent permitted by law, the apps and the website are provided "as is" and "as available", without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement, or uninterrupted operation. We do not warrant that the apps will be free from bugs, that any defects will be fixed, or that any specific feature will continue to be available.

11. Limitation of liability

To the maximum extent permitted by law, ZaatarLABS will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, goodwill, data, or use, arising out of or in connection with these Terms or your use of the apps or website, even if we have been advised of the possibility of such damages.

Where our liability cannot be excluded under applicable law, our total aggregate liability to you for any claim arising out of or relating to these Terms or the apps is limited to the greater of (a) the amount you have actually paid to Apple for the app in the 12 months before the event giving rise to the claim, or (b) USD 50.

Nothing in these Terms limits or excludes our liability for fraud, fraudulent misrepresentation, gross negligence, or any other liability that cannot lawfully be limited or excluded.

12. Indemnity

You agree to indemnify and hold ZaatarLABS harmless from any third-party claim, demand, or loss (including reasonable legal fees) arising from (a) your use of the apps or the website in breach of these Terms, (b) your violation of any law or third-party right, or (c) the records and content you enter into the apps about other people.

13. Intellectual property

The apps, the website, the ZaatarLABS name and logo, the names of each app, and the look and feel of each interface are the property of ZaatarLABS and are protected by copyright, trademark, and other intellectual-property laws. Nothing in these Terms grants you any right to our trademarks or branding beyond the limited use needed to use the apps as intended.

14. Third-party services and links

The apps and the website may include links to, or interact with, services we don't operate (Apple, the App Store, Apple Wallet, iCloud, public exchange-rate APIs, WhatsApp, your email client, and so on). We're not responsible for those services, their availability, or their terms; your interactions with them are governed by their own terms and privacy policies.

15. Privacy

Our collection and use of information are described in our Privacy Policy, which forms part of these Terms.

16. Changes to these Terms

We may update these Terms from time to time. If we make a material change, we'll update the "Effective" date at the top of this page and, where reasonable, post a notice in-app or on this site. Your continued use of the apps or website after a change takes effect means you accept the updated Terms; if you don't agree, please stop using the apps.

17. Governing law and disputes

These Terms are governed by the laws of the United Arab Emirates and, as applicable, the laws of the Emirate of Dubai, without regard to conflict-of-law principles. Any dispute arising out of or in connection with these Terms that the parties cannot resolve informally will be subject to the exclusive jurisdiction of the competent courts of Dubai, UAE — except that we may bring proceedings to protect our intellectual property in any court of competent jurisdiction. If you are a consumer in a country whose mandatory consumer-protection laws give you additional rights, those rights are not affected by this clause.
